camera's &amp; trajectories

[font=Verdana][size=1:f07d77458c]MAX4::I am building an imaginary road in 3D. I would the camera to travel along that road, but the cam needs to rotate and tilt according to the road.

I am converting the trajectory from a line that that i created. I tried the regular cam, it would move but the cam doesn't rotate according to the line. When i use the target cam it works a bit better but somehow i can't really time the target and the cam really well.
